You say that both the LSID and advertising router should have 10 as their first octet when the data is

00 00 22 02
20 01 01 02
20 01 FE 01
80 00 00 10
41 A5 00 20

10 decimal is 0A in hex, but 0A does not appear anywhere in the data. Your statement is either false, or your dump is inaccurate.

In fact, the bytes for the LSID are 20, 01, 01, 02, which corresponds to the decimal numbers 32, 1, 1, 2. That's exactly what your code prints out (32.1.1.2), so there is no error in your code (if your dump is accurate).
